One of my players wants to play a "cannon wielding" Aegis, using a standard musket. We are playing the Emerald Spire module, meaning the group will end at 13th level.
I was trying to stay away from variant multi-classing as Gunslinger since it doesn't look all that helpful, and the player wishes to avoid alchemy cartridges since he doesn't have grit to deal with his gun blowing up in his face like a gunslinger does.
Other than rapid reload, what can a player do to decrease the action requirement for loading a gun?
Cartridges and rapid reload are your only options for increasing reload speed normally.
Consequently that means that you can never full attack with a musket if you don't take three levels in the musket master archetype.
Your Aegis should upgrade that musket to a rifle as soon as possible, since those reload as a free action with just rapid reload.
There is the Shadowshoot weapon property from Blood of Shadows which doesn't need ammo at all, but it forces a low will save on every shot that causes your attack to do minimum damage if the enemy passes it, so it's kind of terrible.
There's also the Pistol of the Infinite Sky, a +5 pistol (priced as a +6 weapon) that never needs to be loaded, so maybe you could eventually adapt a version of that to a musket if none of the above options appeal.
Amateur gunslinger is a feat which gives a little grit to deal with his gun wanting to blow up.
Alternately a Beneficial Bandolier can load a firearm as a swift action.
Empty Quiver Flurry allows for reloading as a free action.
1) If you hit a foe in melee
2) If you are an Elf (Stabbing Shot)Amateur gunslinger is a feat which gives a little grit to deal with his gun wanting to blow up.
Alternately a Beneficial Bandolier can load a firearm as a swift action.
I assume that means that Rapid Reload in no way effects the bandolier?
It's a swift action whatever feats you might have, yeah.
